Patagonia W's Nano-Air Light Vest

The Layer You Never Have to Take Off

That's the whole idea behind the Patagonia W's Nano-Air® Light Vest. It was designed to stay on through the entirety of your aerobic, start-stop mountain day — no stopping to stuff it in your pack, no overheating on the climb, no shivering on the belay.

FullRange® insulation dumps excess heat when you're working hard and holds warmth when you're not. A 100% recycled polyester ripstop shell stretches with you, breathes exceptionally well, and sheds light moisture with a PFAS-free DWR finish. At 170 g, you'll barely notice it's there — until you take it off.

The Details

• 40-g FullRange® Insulation (93% Recycled) — Warm, stretchy, and air-permeable at 35 CFM. Moves excess heat away from the body when the pace picks up.
• 100% Recycled Polyester Ripstop Shell & Lining — Mechanical stretch, exceptional breathability, PFAS-free DWR finish. Microtexture keeps it from sticking to skin.
• Articulated Patterning & Low-Profile Quilting — Engineered for a full range of motion. Nothing bunches, nothing binds.
• Center-Front Zipper with Garage — Soft at the chin, even when zipped to the top.
• Two Handwarmer Pockets + Left-Chest Pocket — All zippered, all low-profile, all harness and pack compatible. The vest self-stuffs into the chest pocket.
• Clean Armholes & Hem — Low bulk, no fuss.
• bluesign® Approved Fabrics — Responsible from shell to insulation.
• Fair Trade Certified™ — Made in Jordan by people who earned a fair premium for their work.
• Weight: 170 g (6 oz)
